  1. 1. Validation of energy efficiency requirements for machine tools and industrial washing machines

    Master-uppsats, KTH/Energiteknik

    Författare :Alexander Brus; [2019]
    Nyckelord :;

    Sammanfattning : Production equipment accounts for a large portion of the energy use from industry. But so far there has been no standardized way of requiring energy efficiency when purchasing a new machine. Scania is therefore implementing energy efficiency requirements in their purchasing process for production equipment. LÄS MER

  2. 2. Characterization of Graphene-Based Anisotropic Conducting Adhesives : A study regarding x-ray sensing applications

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Marcus Gärdin; [2019]
    Nyckelord :Anisotropic conductive adhesive; Graphene; Flip-chip; Graphene oxide; Epoxy composite; Anisotropt ledande adhesive; Grafen; Flip-chip; Grafenoxid; Epoxykomposit;

    Sammanfattning : A common method of cancer treatment is radiation therapy. In radiation therapy, a treatment planning system is made to specify the dose of X-rays needed to eradicate the tumor. To assure the right amount of X-ray dosage a quality assurance is using a phantom containing radiation sensors. LÄS MER

  3. 3. Iron-Based Dye-Sensitized Solar Cells - From Theory to Working Solar Cell

    Master-uppsats, Lunds universitet/Centrum för analys och syntes

    Författare :Linnea Lindh; [2019]
    Nyckelord :Dye-sensitized solar cells; Grätzel cells; solar cells of the future; solar cells of tomorrow; spectroscopy; time-resolved spectroscopy; materials chemistry; materialkemi; Chemistry;

    Sammanfattning : In the hunt for fossile-free energy-harvesting techniques, solar cells constitute one of the most promising techniques. Today, silicon-based solar cells are the dominant technique on the market but even the Silicon solar cell has limitations which means that there is a motivation for developing new solutions. LÄS MER

  4. 4. Ferroelectric Gate-Stack on InAs

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Pontus Littow; [2019]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Modern electronics are becoming more powerful and energy efficient for every new process generation. A key component in electronics is the transistor, which has made this trend possible. For many years the transistor has simply been scaled down.However, that is not possible any longer. LÄS MER

  5. 5. Investigation of thermal conductivity in thin graphite films through time-resolved X-ray diffraction

    Kandidat-uppsats, Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionen

    Författare :Axel Stenquist; [2019]
    Nyckelord :Ultra fast X-ray diffraction; graphite; thin graphite films; thermal conductivity; Physics and Astronomy;

    Sammanfattning : Knowledge about thermal properties of nanoscale graphite is essential in order to realize the many promising applications of carbon based nanomaterials. This thesis reports how samples of thin graphite films on nickel substrates were investigated using time-resolved X-ray diffraction (TRXD) at the FemtoMAX beamline at the MAX IV facility. LÄS MER
